CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is based on and claims priority under 35 U.S.C. § 119(a) of a Korean patent application number 10-2017-0158719, filed on Nov. 24, 2017, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein its entirety.

BACKGROUND 1. Field

The disclosure relates to a technology for radiating a signal in a specific direction.

2. Description of Related Art

An electronic device, such as a smartphone, a wearable device, or the like, which is equipped with an antenna, has been widely supplied as mobile communication technologies develop. The electronic device may transmit/receive various kinds of data (e.g., a message, a photo, a video, a music file, a game, and the like) through an antenna. In particular, since an antenna array has an effective isotropically radiated power (EIRP) greater than one antenna, the antenna array may transmit/receive various kinds of data more effectively.

In addition to the antenna array, other part(s) may be positioned at the electronic device. For example, a display, a printed circuit board (PCB), or the like may be stacked above the antenna array within the electronic device. The display may output various kinds of content (e.g., a photo, a video, and the like), and an application processor (AP), a memory, and the like may be mounted on the PCB.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

SUMMARY

As the size of the electronic device becomes small-sized, a separation distance between the antenna array and the other part(s) may become very short. Since the separation distance between the antenna array and the other part(s) may become very short, the other part(s) may have an influence on a signal which the antenna array radiates.

Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an electronic device for solving the above-described problem and problems brought up in this specification.

For example, the antenna array may radiate a signal in a specific direction, but the other part(s) may distort a direction in which the antenna array radiates the signal. As such, the electronic device may fail to radiate a signal in a specific direction, or signal transmission/reception performance in the specific direction may be markedly reduced.

Alternatively, in the case where the other part(s) distorts a beam pattern of the antenna array, a region (e.g., a null region) where a signal is not radiated may occur.

Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.

Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the disclosure is provided for illustration purpose only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

FIG. 1 is an exploded perspective view of an electronic device according to an embodiment of the disclosure.

Referring to FIG. 1, an electronic device 100 may include a cover glass 110, a rear cover 120, a display 130, a first printed circuit board (PCB) 140, a battery 150, and a plurality of communication devices 161a, 161b, 161c, and 161d.

According to various embodiments, the cover glass 110 (or a front plate) may transmit light generated by the display 130. Also, a user may touch a portion (e.g., a finger) of his/her body on the cover glass 110 to perform a touch (including a contact using an electronic pen). For example, the cover glass 110 may be formed of tempered glass, reinforced plastics, a flexible polymer material, or the like. According to an embodiment, the cover glass 110 may be also referred to as a “glass window.”

According to various embodiments, the rear cover 120 may be coupled with the cover glass 110. As the rear cover 120 is coupled with the cover glass 110, various kinds of parts (e.g., the display 130 and the first PCB 140) included in the electronic device 100 may be protected against an external impact. According to an embodiment, the rear cover 120 may be formed of tempered glass, plastic, and/or metal.

According to various embodiments, the rear cover 120 may include a rear plate (not illustrated), and a side member (not illustrated) surrounding a space between the rear plate and the cover glass 110. In this case, the rear plate and the side member may be removable, or the rear plate and the side member may be coupled to form an integral rear cover.

According to various embodiments, the display 130 may be interposed between the cover glass 110 and the rear cover 120. The display 130 may be electrically connected with the first PCB 140, and may output content (e.g., a text, an image, a video, an icon, a widget, a symbol, or the like) or may receive a touch input (e.g., a touch, a gesture, a hovering, or the like) from the user.

According to various embodiments, various electronic parts, various elements, or various printed circuits, or the like of the electronic device 100 may be mounted on the first PCB 140. For example, an application processor (AP), a plurality of communication processors (CPs) (or modems), a memory, and the like may be mounted on the first PCB 140. According to an embodiment, the plurality of CPs may be processors supporting different communication standards. For example, the plurality of CPs may include a first CP and a second CP. The first CP may be a 4th generation (4G) CP supporting 4G mobile communication, and the second CP may be a 5th generation (5G) CP supporting 5G mobile communication.

According to various embodiments, at least one communication circuit may be positioned at the first PCB 140. The communication circuit may include communication circuits supporting a specified communication standard. For example, the at least one communication circuit may include a first communication circuit and a second communication circuit. The first communication circuit may be an inter frequency integrated circuit (IFIC) supporting 5G mobile communication, and the second communication circuit may be a radio frequency integrated circuit (RFIC) supporting 4G mobile communication. In the disclosure, the first PCB 140 may be referred to as a “first PCB”, a “main PCB,” a “main board,” or a “printed board assembly” (PBA).

According to various embodiments, the battery 150 may convert chemical energy and electrical energy bidirectionally. For example, the battery 150 may convert chemical energy into electrical energy and may supply the converted electrical energy to the display 130 and various components or modules mounted on the first PCB 140. Alternatively, the battery 150 may convert and store electrical energy supplied from the outside into chemical energy. According to an embodiment, a power management module for managing the charging and discharging of the battery 150 may be included in the first PCB 140.

According to various embodiments, each of the plurality of communication devices 161a, 161b, 161c, and 161d may include a communication circuit (e.g., a communication circuit 250 of FIG. 2A) and an antenna array (e.g., a first antenna array 220 of FIG. 2B). The communication circuit 250 may feed the first antenna array 220 to transmit/receive a communication signal (e.g., a signal of a frequency band ranging from 20 GHz to 70 GHz). In the disclosure, the communication circuit 250 may be referred to as a “5G RFIC.” According to various embodiments, the communication circuit 250 may be positioned on the first PCB 140.

According to various embodiments, the communication circuit 250 may transmit/receive a signal of a specific direction by feeding the plurality of communication devices 161a, 161b, 161c, and 161d, respectively. For example, the electronic device 100 may transmit/receive a signal in a first direction by using a first communication device 161a and a second communication device 161b. For another example, the electronic device 100 may transmit/receive a signal in a second direction by using a third communication device 161c and a fourth communication device 161d. In the disclosure, the first direction and the second direction may refer to any direction in which the plurality of communication devices 161a, 161b, 161c, and 161d may transmit/receive a signal.

According to various embodiments, the embodiment illustrated in FIG. 1 is exemplary, and the embodiments of the disclosure are not limited to the illustration of FIG. 1. For example, the number of the plurality of communication devices 161a, 161b, 161c, and 161d included in the FIG. 1, locations of the plurality of communication devices 161a, 161b, 161c, and 161d, and the like are not limited to the illustration of FIG. 1.

In an electronic device according to a comparative example, parts in the electronic device such as a display may affect a beam pattern or the electric field strength of a signal. For example, the parts may distort a direction in which the electronic device according to the comparative example may radiate a signal, and a beam pattern. As such, the electronic device according to the comparative example may fail to radiate a signal in a specific direction, or signal transmission/reception performance in the specific direction may be reduced. In the disclosure, the beam pattern may indicate the electric field strength of a signal which an antenna array radiates.

In the electronic device according to the comparative example, permittivity of a cover glass may be different from permittivity of a rear cover. For example, the cover glass may be formed of glass, and the rear cover may be formed of plastic. Since the permittivity of the cover glass is different from the permittivity of the rear cover, a direction in which a signal is radiated or a beam pattern may be distorted in the process where the signal passes through the cover glass and the rear cover. In particular, the size of the beam pattern may decrease due to the discontinuity of permittivities occurring at a specific portion (e.g., in the vicinity of a contact portion of the cover glass and the rear cover). The quantity of a signal radiated through a region (e.g., a null region) where the size of the beam pattern decreases may be small.

According to an embodiment of the disclosure, a dielectric substance (e.g., a dielectric substance 230 of FIG. 2B) and a conductor (e.g., a conductor 240 of FIG. 2B) may be mounted in each of the plurality of communication devices 161a, 161b, 161c, and 161d in consideration of the influence of the parts. The dielectric substance 230 and the conductor 240 may change a direction, in which the plurality of communication devices 161a, 161b, 161c, and 161d may radiate a signal, and a beam pattern to a specified direction in consideration of parts such as the display 130, the cover glass 110, or the rear cover 120. As such, the electronic device 100 according to an embodiment of the disclosure may radiate a signal in a specific direction (e.g., the first direction and the second direction), and may improve signal transmission/reception performance of the direction.

In the disclosure, the plurality of communication devices 161a, 161b, 161c, and 161d illustrated in FIG. 1 may be mounted in a tablet, a wearable device, a router, or the like in addition to the electronic device 100. Also, in the disclosure, the description given with reference to FIG. 1 may be identically applied to components having the same reference numerals/marks as the electronic device 100 described with reference to FIG. 1.

FIG. 2A is an enlarged view of a first communication device according to an embodiment of the disclosure. FIG. 2A is a view for describing a structure of the first communication device 161a in detail.

FIG. 2B is a sectional view of a first communication device according to an embodiment of the disclosure. FIG. 2B shows a cross section of a communication device taken along a line A-A′ of FIG. 2A.

FIG. 2C is a sectional view of a first communication device according to an embodiment of the disclosure. FIG. 2C shows a cross section of a communication device taken along a line B-B′ of FIG. 2A.

Referring to FIGS. 2A, 2B, and 2C, the first communication device 161a may include a second PCB 210, the first antenna array 220, the dielectric substance 230, the conductor 240, the communication circuit 250, and a second antenna array 260 that includes a plurality of second radiators 261, 262, 263, and 264. In the disclosure, the dielectric substance 230 may be referred to as a dielectric substance structure, and the conductor 240 may be referred to as a conductor structure.

According to various embodiments, the first antenna array 220 may be mounted at the second PCB 210. According to an embodiment, the second PCB 210 may include a plurality of layers, and at least any one of the plurality of layers may include a dielectric substance (e.g., plastic). In the disclosure, the second PCB 210 may be referenced as a “5G module PCB.”

According to various embodiments, the first antenna array 220 may be positioned on a periphery of the second PCB 210. For example, as illustrated in FIG. 2A, the first antenna array 220 may be positioned adjacent to a first side surface 210-1 of the second PCB 210. Although not illustrated in FIG. 2A, the first antenna array 220 may be positioned adjacent to a second side surface 210-2 of the second PCB 210.

According to various embodiments, the first antenna array 220 may include a plurality of first radiators 221, 222, 223, and 224. Each of the plurality of first radiators 221, 222, 223, and 224 may be positioned in the second PCB 210. For example, each of the plurality of first radiators 221, 222, 223, and 224 may not be exposed to the outside of the second PCB 210 because the plurality of first radiators 221, 222, 223, and 224 are positioned in the second PCB 210. In the disclosure, a radiator may be referred to as an “antenna element.”

According to various embodiments, the first communication device 161a may include the second antenna array 260. The second antenna array 260 may be positioned on a lower surface (or a surface facing the rear cover 120) of the second PCB 210, or may be positioned adjacent to the lower surface.

According to various embodiments, a direction of a signal which the second antenna array 260 may transmit/receive may be different from a direction of a signal which the first antenna array 220 may transmit/receive. For example, the second antenna array 260 may radiate a signal mainly in a-z direction, and the first antenna array 220 may radiate a signal in the first direction as a main radiation direction.

According to various embodiments, the dielectric substance 230 may be positioned above the first antenna array 220. The conductor 240 (e.g., metal) may be positioned below the first antenna array 220. According to various embodiments, the conductor 240 may be positioned on the same plane as the second antenna array 260.

According to various embodiments, in FIGS. 2A to 2C, a shape of the first communication device 161a, a configuration of the first communication device 161a, the number of the plurality of first radiators 221, 222, 223, and 224, locations of the plurality of first radiators 221, 222, 223, and 224, and the like are exemplary, and the embodiments of the disclosure are not limited to the illustration of FIGS. 2A to 2C. Also, in the disclosure, the description of the first communication device 161a given with reference to FIGS. 2A to 2C may be identically applied to the second communication device 161b, the third communication device 161c, and the fourth communication device 161d.

FIG. 3 is a sectional view of an electronic device according to an embodiment of the disclosure. FIG. 3 is a sectional view of the electronic device 100 where the first communication device 161a illustrated in FIG. 2A is mounted.

In an electronic device according to a comparative example, permittivity of a cover glass may be different from permittivity of a rear cover. Since the permittivity of the cover glass is different from the permittivity of the rear cover, a direction in which a signal is radiated or a beam pattern may be distorted in the process where the signal passes through the cover glass and the rear cover. For example, the size of the beam pattern may decrease due to discontinuity of permittivities occurring at a specific portion (e.g., in the vicinity of a contact portion of the cover glass and the rear cover). The quantity of a signal radiated through a region (e.g., a null region) where the size of the beam pattern decreases may be small.

Referring to FIG. 3, as the dielectric substance 230 is mounted at the first communication device 161a according to various embodiments of the disclosure, the first communication device 161a may make attenuation of a signal small due to the null region.

According to various embodiments of the disclosure, as the conductor 240 is mounted at the first communication device 161a, the first communication device 161a may radiate a signal mainly in a third direction. For example, the conductor 240 may reflect a signal radiated from the first antenna array 220, and thus, a main radiation direction of the signal radiated from the first antenna array 220 may be changed to the third direction. The third direction may be only a main direction in which the first antenna array 220 radiates a signal, and the first antenna array 220 may also radiate a signal, the strength of which is weaker than in the third direction, in the first direction and a fourth direction. As such, a signal which the first antenna array 220 radiates may form a beam pattern of a specific shape (e.g., an oval shape).

According to various embodiments of the disclosure, a main radiation direction of the first antenna array 220 may be changed to the third direction by the conductor 240. In this case, the strength of a signal which the first antenna array 220 radiates in the fourth direction may be weaker than the strength of a signal which the first antenna array 220 radiates in the third direction when the first direction is a main radiation direction. In this case, the second antenna array 260 may cover a fourth-direction signal which decreases.

FIG. 4A is a view illustrating a beam pattern of a communication module not assembled at a housing according to an embodiment of the disclosure. In the disclosure, a communication module 10 according to a comparative example may mean a communication module which does not include the dielectric substance 230 and the conductor 240 of FIG. 3. A beam pattern illustrated in FIG. 4A may indicate a beam pattern of the communication module 10, which is measured in a state where the beam pattern is not affected by any other parts.

FIG. 4B is a view illustrating a beam pattern of a communication device according to an embodiment of the disclosure. A beam pattern illustrated in FIG. 4B may indicate a beam pattern of the first communication device 161a (or the first antenna array 220) measured in the case where the conductor 240 is included under the condition of FIG. 4A. In this case, a main radiation direction may be changed from the first direction to the third direction.

FIG. 4C is a view illustrating a cross section and a beam pattern of an electronic device according to an embodiment of the disclosure. FIG. 4C shows a beam pattern formed by the first communication device 161a (or the first antenna array 220) in the case where the first communication device 161a according to an embodiment of the disclosure is positioned in the electronic device 100.

Referring to FIG. 4A, the communication module 10 according to the comparative example may be a communication module which is not assembled at a housing and does not include the conductor 240. The communication module 10 may radiate a signal in a direction (e.g., the first direction), which is parallel to the communication module 10, as a main radiation direction. Also, since the communication module 10 according to the comparative example is not assembled at the housing and does not include the conductor 240, a beam pattern 410 may maintain radiation performance in the first direction, the third direction, and the fourth direction.

Referring to FIG. 4B, since the first communication device 161a according to an embodiment of the disclosure includes the conductor 240, the first communication device 161a may radiate a signal mainly in an oblique direction (e.g., the third direction) with respect to a plane where the first communication device 161a is positioned. For example, as the conductor 240 reflects a signal radiated toward a rear surface, a main radiation direction in which the signal is radiated may be changed from the first direction to the third direction.

According to various embodiments, as the conductor 240 is positioned at the first communication device 161a, a direction of a beam pattern 420 may be changed. For example, as a main radiation direction of a signal is changed to the third direction, the beam pattern may be formed between approximately −30° and approximately 150°. The size of the beam pattern 420 may be somewhat small at approximately −30° and approximately 150°, but may maintain 9 dB between 0° and 120°.

Referring to FIG. 4C, if the first communication device 161a according to an embodiment of the disclosure is positioned in the electronic device 100, the first communication device 161a may have an influence on the cover glass 110, the rear cover 120, the display 130, the first PCB 140, or the like. A radiation pattern 440 of a dotted line may be a radiation pattern of the first antenna array 220 when the first communication device 161a is positioned at the electronic device 100 without the dielectric substance 230 and the conductor 240. A null region may be formed toward a contact point of the cover glass 110 and the rear cover 120, and the radiation pattern 440 may be biased toward a lower end of the drawing. A radiation pattern 430 of a solid line may be a radiation pattern of the first antenna array 220 when the dielectric substance 230 and the conductor 240 are applied to the first communication device 161a. A radiation direction may be changed toward an upper end of the drawing by the conductor 240, and the null region may be decreased by the dielectric substance 230. A lower end portion of the drawing may be covered by a radiation pattern of the second antenna array 260. The electronic device 100 according to various embodiments of the disclosure may include the conductor 240 and the dielectric substance 230 in the first communication device 161a, thereby making it possible to make the reduction of performance due to any other part(s) or housings small or to complement the performance.

FIG. 5A is a view illustrating a communication device according to an embodiment of the disclosure. FIG. 5B is an enlarged view of a communication device according to an embodiment of the disclosure. FIG. 5B is an enlarged view of a partial region 550 illustrated in FIG. 5A according to an embodiment of the disclosure.

Referring to FIGS. 5A and 5B, a communication device 500 may include a PCB 510 (or a second PCB), a first antenna array 521, a second antenna array 522, a first dielectric substance 531, a second dielectric substance 532, a first conductor 541, and a second conductor 542.

According to various embodiments, the PCB 510 may be configured to mount the first antenna array 521, the second antenna array 522, the first dielectric substance 531, the second dielectric substance 532, the first conductor 541, and the second conductor 542. The description of the second PCB 210 given with reference to FIG. 2A may also be applied to the PCB 510.

According to an embodiment, the first antenna array 521 and the second antenna array 522 may be positioned on a periphery of the PCB 510. Each of the first antenna array 521 and the second antenna array 522 may include a plurality of antenna radiators (or antenna elements).

According to various embodiments, the first dielectric substance 531 may be positioned above the first antenna array 521, and the second dielectric substance 532 may be positioned above the second antenna array 522. The first dielectric substance 531 may make distortion of a signal radiated from the first antenna array 521 small. The second dielectric substance 532 may make distortion of a signal radiated from the second antenna array 522 small. For example, a null region occurring at a contact point of a front glass and a rear cover of a housing, which have different permittivities, may become small.

According to various embodiments, the first conductor 541 may be positioned below the first antenna array 521, and the second conductor 542 may be positioned below the second antenna array 522. The first conductor 541 may reflect a signal radiated from the first antenna array 521 and may change a direction of the signal. The second conductor 542 may reflect a signal radiated from the second antenna array 522 and may change a direction of the signal. According to various embodiments of the disclosure, the first conductor 541 and the second conductor 542 may include a conductive sheet.

Below, a detailed description will be given with reference to FIG. 5B. Each of radiators included in the second antenna array 522 may be extended from a side surface of the PCB 510. For example, a portion of a radiator 522-1 (included in the second antenna array 522) may be extended in a direction perpendicular to the side surface of the PCB 510. The remaining portion of the radiator 522-1 may be extended in a direction parallel to the side surface of the PCB 510. In the disclosure, the description given with regard to the second antenna array 522 may also be applied to the first antenna array 521.

According to various embodiments, the second dielectric substance 532 may be positioned above the second antenna array 522. A thickness of the second dielectric substance 532 may be thicker than a thickness of the PCB 510. According to an embodiment, the second dielectric substance 532 may be formed of substantially the same material (e.g., plastic) as the PCB 510. In the disclosure, the description given with regard to the second dielectric substance 532 may also be applied to the first dielectric substance 531.

According to various embodiments, the second conductor 542 may be positioned below the second antenna array 522. A thickness of the second conductor 542 may be relatively thinner than a thickness of the second dielectric substance 532 and the PCB 510. According to an embodiment, the second conductor 542 may be formed of a conductive material unlike the second dielectric substance 532 and the PCB 510. In the disclosure, the description given with regard to the second conductor 542 may also be applied to the first conductor 541.

FIG. 6A is a view illustrating a mounting location of a communication device according to an embodiment of the disclosure. FIG. 6A shows how the communication device 500 illustrated in FIG. 5A is mounted on a rear cover 610.

FIG. 6B is a view illustrating a communication device and a PCB according to an embodiment of the disclosure. FIG. 6B shows how a PCB 620 (or a first PCB) is mounted above the communication device 500 illustrated in FIG. 5A. According to various embodiments, a separation distance between the PCB 620 and the rear cover 610 may be more distant than a separation distance between the communication device 500 and the rear cover 610. In the disclosure, the description given with reference to FIG. 5 may be applied to components which have the same reference numerals (or marks) as the communication device 500 illustrated in FIG. 5.

Referring to FIGS. 6A and 6B, an electronic device 600 may include the rear cover 610 and the communication device 500. The rear cover 610 may form an appearance of a rear surface of the electronic device 600. The description given with regard to the rear cover 120 illustrated in FIG. 1 may also be applied to the rear cover 610.

According to various embodiments, the communication device 500 may be positioned adjacent to a periphery of the rear cover 610. For example, the communication device 500 may be interposed between a first side surface 611 and a second side surface 612. According to an embodiment, the communication device 500 may be attached to the rear cover 610 through an adhesive material.

Although not illustrated in FIG. 6A, the electronic device 600 may include a plurality of communication devices. Each of the communication devices may be positioned adjacent to a periphery of the rear cover 610. For example, the electronic device 600 may include four communication devices, and each of the four communication devices may be positioned on a corner of the rear cover 610. Also, each of the communication devices may be attached to the rear cover 610 through an adhesive material.

According to various embodiments, the PCB 620 (or a first PCB) may be positioned above the communication device 500. For example, since the first dielectric substance 531 and the second dielectric substance 532 have a given thickness, the PCB 620 may be mounted above the first dielectric substance 531 and the second dielectric substance 532. As such, the PCB 510 (or a second PCB) of the communication device 500 and the PCB 620 (or a first PCB) may have a separation distance as much as the thickness of the first dielectric substance 531 and the second dielectric substance 532. The description of the first PCB 140 given with reference to FIG. 1 may also be applied to the PCB 620.

According to various embodiments, as the electronic device 600 includes the first and second dielectric substances 531 and 532 and the first and second conductors 541 and 542, the electronic device 600 may make reduction of performance due to a housing and any other parts small or may complement the performance. For example, as the first conductor 541 is coupled to the first antenna array 521, a direction in which the first antenna array 521 may radiate a signal may be changed. The first antenna array 521 may radiate a signal mainly in the third direction in a state where the first conductor 541 is coupled to the first antenna array 521.

According to various embodiments, as the second conductor 542 is combined with the second antenna array 522, a direction in which the second antenna array 522 may radiate a signal may be changed. The second antenna array 522 may radiate a signal mainly in a fifth direction in a state where the second conductor 542 is combined with the second antenna array 522.

In the disclosure, the description given with reference to FIGS. 6A and 6B may be applied to components which have the same reference numerals (or marks) as the electronic device 600 illustrated in FIGS. 6A and 6B.

The communication circuit 730 may be positioned at the PCB 510. The communication circuit 730 may feed the first antenna array 521 and the second antenna array 522. In the disclosure, the description of the communication circuit 250 given with reference to FIG. 2A may also be applied to the communication circuit 730 of FIG. 7.

In the case where the communication circuit 730 feeds the first antenna array 521, the first conductor 541 positioned below the first antenna array 521 may reflect a signal radiated from the first antenna array 521. As such, the first antenna array 521 may radiate a signal in the third direction, not in the first direction, as a main radiation direction.

According to various embodiments, the additional dielectric substance 740 may compensate for a permittivity difference between the cover glass 710 and the rear cover 720. For example, as the additional dielectric substance 740 is interposed between the cover glass 710 and the rear cover 720, a region (e.g., a null region) where the size of a beam pattern decreases may be prevented from occurring.

The electronic device 700 illustrated in FIG. 7 is only an embodiment, and the embodiments of the disclosure are not limited to illustration of FIG. 7. For example, it may be possible to decrease the null region by adjusting a thickness of the cover glass 710 and/or the rear cover 720.

Referring to FIG. 9, the wireless communication module 892 may include a magnetic secure transmission (MST) communication module 910 or a near field communication (NFC) communication module 930, and the power management module 888 may include a wireless charging module 950. In this case, an antenna module 997 may separately include a plurality of antennas including an MST antenna 997-1 connected with the MST communication module 910, an NFC antenna 997-3 connected with the NFC communication module 930, and a wireless charging antenna 997-5 connected with the wireless charging module 950. To avoid redundancy, additional description associated with components which are the same as the components of FIG. 8 will be omitted or will be briefly described.

The MST communication module 910 may receive a signal (e.g., a signal including control information or payment information) from the processor 820, may generate a magnetic signal corresponding to the received signal through the MST antenna 997-1, and may transmit the generated magnetic signal to the external electronic device 802 (e.g., a POS device). According to an embodiment, for example, the MST communication module 910 may include a switching module (not illustrated) including one or more switches connected with the MST antenna 997-1, and may control the switching module to change a direction of a voltage or a current to be supplied to the MST antenna 997-1. A direction of a magnetic signal (e.g., a magnetic field) to be transmitted to the external electronic device 802 through the short-range wireless communication (e.g., the first network 898) may be changed, for example, by transmitting the magnetic signal through the MST antenna 997-1. The magnetic signal transmitted with the direction changed may cause a form and an effect which are similar to those of a magnetic field generated while (or when) a magnetic card is swiped by a card reader of the external electronic device 802. According to an embodiment, payment-related information and a control signal received from the external electronic device 802 in the form of the magnetic signal may be transmitted, for example, to a server (e.g., the server 808) through the second network 899.

The NFC communication module 930 may obtain a signal (e.g., control information or payment information) from the processor 820, and may transmit the obtained signal to the external electronic device 802 through the NFC antenna 997-3. According to an embodiment, the NFC communication module 930 may receive a signal (e.g., a signal including control information or payment information) transmitted from the external electronic device 802 through the NFC antenna 997-3.

The wireless charging module 950 may wirelessly transmit a power to the external electronic device 802 (e.g., a mobile phone or a wearable device) through the wireless charging antenna 997-5, or may wirelessly receive a power from the external electronic device 802 (e.g., a wireless charging device). The wireless charging module 950 may support various wireless charging manners, for example, including a magnetic resonance manner or a magnetic induction manner.

According to an embodiment, some of the MST antenna 997-1, the NFC antenna 997-3, or the wireless charging antenna 997-5 may mutually share at least a portion of a radiation unit (or radiator). For example, a radiation unit of the MST antenna 997-1 may be used as a radiation unit of the NFC antenna 997-3 or the wireless charging antenna 997-5, and vice versa. In the case where the MST antenna 997-1, the NFC antenna 997-3, or the wireless charging antenna 997-5 shares at least a partial region of a radiation unit, the antenna module 997 may include a switching circuit (not illustrated) for selectively connecting or separating (e.g., opening) at least some of the antennas 997-1, 997-3, and 997-5 under control of the wireless communication module 892 (e.g., the MST communication module 910 or the NFC communication module 930) or the power management module 888 (e.g., the wireless charging module 950). For example, in the case where the electronic device 801 uses a wireless charging function, the NFC communication module 930 or the wireless charging module 950 may control the switching circuit such that the at least a partial region of the radiation unit shared by the NFC antenna 997-3 and the wireless charging antenna 997-5 is temporarily separated from the NFC antenna 997-3 and is connected only with the wireless charging antenna 997-5.

According to an embodiment, at least a part of functions of the MST communication module 910, the NFC communication module 930, or the wireless charging module 950 may be controlled by an external processor (e.g., the processor 820). According to an embodiment, specified functions (e.g., a payment function) of the MST communication module 910 or the NFC communication module 930 may be performed in a trusted execution environment (TEE). The TEE, according to various embodiments, may be, for example, an execution environment in which at least a portion of a specified region of the memory 830 is assigned to perform a function (e.g., a financial transaction or a private information related function) needing a relatively high level of security and an access to the specified region is separately and restrictively allowed, for example, depending on an access subject or an application to be executed.
